TYPEWRIIING MACHINE.

Application filed July 10, 1924. Serial No. 725,129.

This invention relates to manifolding upon fan-fold paper work-webs intypewriting machines, particularly those having revoluble platens. I

The usual practice in such-types of machines is to locate individualsheets of carbon between the plies or folds of the web in a manner whichcalls for straightening out the web at frequent intervals to permit theshifting of the carbon-sheets along the web from the typed portionthereofto the untyped portion of the same. An occasional incident tosuch shifting of the carbon-sheets has been the maladjustment ofindividual carbon-sheets relatively to others between the plies of saidweb. In orderto overcome the foregoing drawback of shifting thecarbon-sheets, as is now found necessary in the present marketedUnderwood fan-fold machine, 7 the present mechanism is provided, whichis primarily designed to simplify construction in a manner that rendersunnecessary the raising of the platen for-the straightening of the web,or shifting the same to release the carbon-sheets from contact with theplies of the web. I

Another object of the invention is to provide means for automatically ormanually measuring predetermined uniform lengths of the web as the same,after being printed, is progressively carried beyond the platen in orderto assure that these predetermined typed portions of the web maycorrespond to the length of the printed forms on the web prior tosevering them from the'untyped portions thereof.

A still further object of the invention is to provide various economiesin the construction and operation of signed to produce simultaneouslytyped impressions upon the several plies ofa fanfold web, lookingtowards the ultimate separation of each member of a series of for-ms.printed consecutively upon said web.

It is a still further object of the invention to attain the above namedresults by the aid of inlr i-ibbons instead" of carbon-sheets as themanifolding medium gfor' producing 81- mulwnewsly typ d mp i ns upon"the separate jplies of a fan-fold a mechanism depressions upon all thepliesof a RSEY, ASSIGNOR TO UNDERWGOD TYPE- Other features andadvantages will hereinafter appear.

Referring to the drawings, 10 designates the manifolding sheets orstrips which are employed in the form oftypewriter ribbons,

which ribbons are auxiliary a main ribbon found in a typewriter.stretches of, ink-ribbon are arranged to positioned longitudinally ofthe machirreflsq as to be disposed at the'delivery side o platen alongthe printing l ne.

to the usual These It is (Olly templated' to use as many stretches ofribbon as may be necessary to produce typed web. The ribbon-Qarriers im:t n-f d are b eede de ignated l1, and each QilSiStS Q? a l ltg lllidinally extending co-extensively w th the e the whwh serves to positionand support by n ns integral Hooks 1-3 fer-madapes 1*?5' QPP a mi bla 2ex ending .mounted upon bracket-pieces ends, these hooks receiving theloops 15 formed terminally upon the ribbon 10, which ribbon is heldagainst downward displacement from the blades by means of the bills 1 1-of the hooks. It will be seen that the ribbons are thus removablymounted upon their carriers.

A fan-fold web 1O is preferably employed in the typewriting machine uponwhich the attachment and invention is mounted, and this web isintegrally provided transversely thereof, continuously of its entirelength, with alternate folds E and F, providing a series of longitudinalplies designated A, B, O, D, and so forth, said folds being open atalternately opposite ends thereof for the insertion thereinto of thecarbon ribbons 10, which ribbons may easily and removably be introduced,one entering from one side of the web and the other from the other sidethereof, and so on, so that one loop end of each ribbon 10 will projectbeyond and out-- side the folds of the web, the other being encased inone of the folds of the web, as shown clearly in Fi 'ures 4t and 5. Thisresults in the free ends of the ribbons and the hooks 13 0f theribbon-carriers being supported in staggered relation with respect tothe longitudinal edges of the fan-fold web 10*; however, the ink-ribbons10, which are arranged in longitudinal alignment within the folds of theweb-extend throughout the effective transverse area of the web, theseribbons acting as a unit for the purpose of receiving simultaneousstrokes from the type-bars 35 of the machine.

16 designates the brackets upon which the ribbon-carriers 11 aredetachably secured. 17 designates the platen mounted on a shaft 18 inthe usual bearings of the machine, having a hand-wheel 19 for revolvingthe same manually, and. also carrying the line-space ratchet-wheel 47.Ears 20 extend preferably integrally and upwardly from the hooked endsof the ribboncarriers 11, so as to extend laterally outwardly thereof,and are removably secured upon the brackets 16 by binding screws 21,which are provided with the usual. nuts. The brackets 16 are 22, whichare operatively positioned adjacent the platenshaft 18 at the oppositesides of the machine, and which bracket-pieces are secured to each otherby a cross-bar 22. The left-hand one of the bracket-pieces 22 carries apin 23 projecting preferably in a spiral groove 24 or cam surface formedupon a cam 25 carried by the platen-shaft 18, by means of which cammechanism a horizontal movement is imparted to the ribbon-carriers 11for a purpose to be hereinafter explained.

The bracket-pieces 22 carry headed studs 27 formed on the pins 23, whichproject into a diagonal slots 28 formed upon a slotted portion 28 formedupon the depending bear form designate the front and rear feed-rolls,which are retractibly engageable with the platen and serve to provide atensioning means for holdlng the web in progressive feeding on gagementagainst the platen, so that the web may be carried along over the sideof the platen in arched manner, as shown part-icu larly in Figures 1 and2 at 31.

32 designates a slidable gage mounted upon a shelf-bar or gage-bar 1awhich forms a restfor the advancing typed portion of the web j ustemerging from beyond the printing line of the machine. The gage islocked in adjusted position upon the shelf-bar by the usual thumb-screw33, and the gage has an abutment or stop 34 for arresting the progressof the approaching end of a typed portion of the web at this point, soas to measure of and set apart a predetermined uniform length ofthistyped portion of the web. 35 designates the type-bars which operate inthe conventional manner against the conven tional typewriter ribbon 38,which latter vibrates up and down in front of the platen at the typestrokes, and with reference to which the ribbons 10 are auxiliary. Thetype-bars on impinging upon the main ribbon 38 also make impressionsupon the ribbons 10, which shift relatively to the printing types in amanner which will be readily understood. In order to sever or detacheach of a number of consecutive forms printed upon said fan-fold web 1Oat uniintcrvals apart, is also employed, consisting of a tearing-offflnife 39 whch is located immediately above the ribbons and blades, sothat the latter may remain in their positions between the folds of theuntyped web. A knife-supporting arm 40 may be fixed in position, or thesame may be pivotally supported so as to move from the dotted lineinoperable position shown in Figure 2 to the full line operable positionshown in the same figure. It will also be. noticed that the tworibbon-cara cutting means llO rying brackets 16 (one at each side of theshown in Figures 1 and 2, in order to hold tact with the platen. A stoppin 43 on the knife-supporting arm 40 rests upon a knife carrying arm 43supported on the platenframe to cause the knife 39 to occupy its properposition at a point directly below the point where the gage 32 is fixed,so that the web, as it extends between the knife 39, when in operableposition, and a point Where the gage 32 is located, represents thealready typed portion of the form printed upon the web, enabling thisportion to, be drawn forwardly against the knife so as to be severedtherefrom. WVhen' the knife is not in use it may be swung out of theway, es pecially when the ribbon-carriers are being attached or detachedfrom the machine. The cams 25 and cams 28 are responsible for prolongingthe life of each of the lengths of ribbons, causing the type-bars toengage different, points vertically and horizontally of the ribbons. Thecam mechanism also provides means. causing. the blades and ribbons toswing forwardly to. and fro in a direction universally of the platen,reducing eventually the paths of contact of the type-bars upon all ofthe ribbons designated M and N in Figures 8- and 9, which illustrate thefact that the major portion of the height of the V ribbon receives therepeated strokes of the type-bars, enabling the ribbons to be graduallyused up. all over their area.

In operation the web 10 is lifted up and fed along down over thepaper-table 36, passing between the front and rear feedrolls, and theweb being thus progressively fed forward around the under side of the"platen 17. Thereupon the ink-ribbon blades 12' may be inserted in.alternate directions, as, shown in Figure 4, between the plies of thefan-fold web and secured to the platenframe by means of the brackets 16.The typing then takes. place and the web isfed past the ribbons line byline by the usual line-spacing mechanism, which mechanism also times theoperation of the cam mechanism. When the typing of a form is com pleted,the advancing end of a web' may be manually drawn up to the gage 82 tomeasure'the length of the form, or the same will take placeautomatically if the web is properly arched; in any event,-whenthe freeend of the web is stopped by the gage, this portion is thentorn off,after. engaging theqknife-bar 39-, so that the untyped; portions of the.web will remain snugly their positions behind andbetween the typewriterribbons. which are properly nested and sandwiched between these plies.In this Way by rotating the platen, the plies of the web may be .m'ovedthrough the spaces between the. ribbons 10,. and to severing. position,and

' by k epi g; the p at n mmova e, wWPI Q will remain stationary in thesespaces so as to be engaged against the ribbons during the typingoperation:

In some cases transparentor tissue paper 48, shown in Figure 5, may beused for the fan-fold web, so that two plies H and I may fall betweenthe adjacent ribbon stretches .insteadof the usual single ply. Theinkribbon causes a typed mpression in this instance to, appear upon bothplies with which it contacts, and similarly the transparency of thepaper will permit the typing to, be read after the forms are torn off;

At Figures 1 and 2, it will be seen that the ribbon-carrying arms 11have their ribbon-attaching billsv or fingers 14 slightlycurved toconform to the curvature of the platen, so that they may readily bemoved up and down, in the web-folds, in front of the platen. by'means ofthe ribbon-carry mg frame, which, it will be remembered, is pivoted onthe platen-axle. It will further be seen that the arms 12 extendtangentially a short distance: away from the platen. If the knife: 39occupied a permanently fixed position during the up-and-down swingingmovement of the ribbon-shifting frame, the length of the web from theprinting line to the edge of the knife would be increased and decreasedslightly due to a bulge which would be-created in the web by the ribboncarrying arms 12- in their lowermost positions. To, avoid-such bulge inthe web, or, in other words, to keep the distance from the printingline, to the edge of the knife always the same, the knife is supportedupon knife-carrying arms 43', each knife-carrying arm being pivoted on astud 50' secured to a downwardextension 51 of the bracketplate- The axesof the studs are in alignment with each other and in alignment with. theprinting line, so that the knifecarrying arms 43' may be swung about thestudstomove the knife toward or away from theplaten as the ribbons moveup and down respectively, I It willbe understood that the bulge createdin the web by the ribbon carrying arms when the ribbons are loweredisrtoo small to have any effecton the gaging of the sheet against thegage; 32. Consequently'the gage- 32- is supported on the gage-bar44which' is relatively fixed. The cross-bar 22% which forms part of theribbon-carrying frame,-

is bent back sulficiently so as not to obstruct the pat-h of the web. 31when said ribboncarrying frame is in its. lowermost position, Figure 2.p a v From the foregoing it will beunderstood that there is providedmeans entending into.

a gage at the front of the platen to measure a stretch of work-web withreference to a knife, which web is fed between the auxil iary ribbons onthe typewriter carriage, and that there are two supports on eachribboncarrier over which the ribbons may be sprung so as to be held tautbetween said supports to overcome any tendency of the ribbons to feedwith the work-web.
